A Hinge Instead of a Lift-Off Lid

Instead of a lift-off lid, the two halves are joined along one edge and swing open like a clamshell, so the bottle stays anchored in one cavity while the opposite half acts as a hinged cover rather than a separate piece to misplace. Pulp on this run is pigmented a muted blue straight through the fiber, not surface-coated, so the tone holds even if the edge chips during unpacking. The dropper bottle's narrow neck sits in a raised collar molded slightly higher than the surrounding cavity floor.

A Sleeve That Locks the Halves Shut

A sleeve slides over the closed clamshell and locks the two halves shut without a separate clasp or elastic band, relying on friction fit against the molded ridges along each half's outer edge. Because this friction-fit sleeve carries the printed ingredient list and brand mark, the blue pulp shell itself stays free of print registration issues that come with printing directly on textured fiber.

One Cavity Shape, Several Bottle Sizes

Cavity height suits a standard essential oil bottle, roughly 10 to 15ml, though the hinge point can shift to accommodate a taller vial without redesigning the whole shell. Brands sourcing this hinged clamshell format alongside cream jar or soap packaging keep a consistent blue tone across a full skincare line while varying only the internal cavity per bottle shape.
